Right-handed sneutrinos as self-interacting dark matter in supersymmetric economical 3-3-1 model
In this work we show that the supersymmetric economical SU(3)C ⊗ SU(3)L ⊗ U(1)X(33-1) gauge model has a realistic candidate for self-interacting dark matter. In the model under consideration, the right-handed sneutrino is in bottom of the triplet, which is a singlet of the Standard Model SU(2)L group. In addition, the right-handed sneutrino is the lightest slepton. By these properties, the righ...

متن کاملAlternatives to Dark Matter 3
It has long been known that Newtonian dynamics applied to the visible matter in galaxies and clusters does not correctly describe the dynamics of those systems. While this is generally taken as evidence for dark matter it is in principle possible that instead Newtonian dynamics (and with it General Relativity) breaks down in these systems. Indeed there have been a number of proposals as to how ...
متن کامل0 v 1 1 8 Ju l 2 00 3 Cosmological constraints on a dark matter – dark energy interaction
It is generally assumed that the two dark components of the energy density of the universe, a smooth component called dark energy and a fluid of nonrelativistic weakly interacting particles called dark matter, are independent of each other and interact only through gravity. In this paper, we consider a class of models in which the dark matter and dark energy interact directly. The dark matter p...
متن کامل5 v 1 1 1 Se p 20 03 PROJECT OF A SUPERFLUID 3 HE DETECTOR FOR DIRECT DETECTION OF NON - BARYONIC DARK MATTER : MACHE 3
MACHe3 (MAtrix of Cells of superfluid Helium 3) is a project of non-baryonic Dark Matter search using superfluid 3 He as sensitive medium. Simulations on a high granularity matrix show very good rejection against background events. First results on a prototype cell are very encouraging. Neutron detection has been highlighted as well as cosmic muon detection. A phenomenological study has been do...
